CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority and benefit of Korean Patent Application No. 10-2014-0127164 filed on Sep. 23, 2014, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

The present disclosure relates to a multilayer ceramic capacitor and a board having the same.

A multilayer ceramic capacitor (MLCC), a multilayer chip electronic component, may be used for various electronic apparatuses due to advantages thereof, such as a small size, high capacitance, and ease of mounting.

For example, a multilayer ceramic capacitor may be used as a chip type condenser installed on the boards of various electronic products such as display devices including liquid crystal displays (LCDs), plasma display panels (PDPs), and the like, as well as computers, personal digital assistants (PDAs), and mobile phones, serving to charge electricity in the batteries thereof or discharge electricity therefrom.

Multilayer ceramic capacitors may have a structure in which a plurality of dielectric layers and internal electrodes having different polarities with respective dielectric layers interposed therebetween are alternately disposed.

In this case, since the dielectric layer has piezoelectric properties, when a direct current (DC) or alternating current (AC) voltage is applied to the multilayer ceramic capacitor, a piezoelectric phenomenon may occur between the internal electrodes, thereby causing periodic vibrations while expanding and contracting a volume of a ceramic body according to the frequency thereof.

These vibrations may be transferred to the board through external electrodes of the multilayer ceramic capacitor and solders connecting the external electrodes and the board to each other, such that the entire board may act as a sound reflecting surface, whereby vibration sound, commonly known as noise, may occur.

This vibration sound may correspond to an audio frequency within the range of 20 to 20,000 Hz causing listener discomfort. This vibration sound causing listener discomfort, as described above, is known as acoustic noise.

In addition, as noiseless components have been provided in electronic equipment, the acoustic noise caused by the multilayer ceramic capacitor as described above may appear relatively more significantly.

Moreover, when equipment is operated in a relatively silent environment, users may perceive such acoustic noise as equipment component failure.

In addition, in the equipment having voice circuits, acoustic noise may be overlapped with voice output, which may cause a problem in which equipment has deteriorated quality in audio output.

SUMMARY

An aspect of the present disclosure may provide a multilayer ceramic capacitor having reduced acoustic noise and a board having the same.

According to an aspect of the present disclosure, a multilayer ceramic capacitor and a board having the same are provided. The multilayer ceramic capacitor may include a ceramic body including internal electrodes stacked in a width direction of the ceramic body and having lead-out portions formed on ends thereof, and external electrodes disposed on portions of end surfaces of the ceramic body in a length direction to be connected to the lead-out portions of the internal electrodes, and terminal electrodes coupled to both end portions of the ceramic body and including horizontal portions disposed below the ceramic body and vertical portions spaced apart from the end surfaces of the ceramic body in the length direction and connected to the external electrodes.

DETAILED DESCRIPTION

Exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

The disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the drawings, the shapes and dimensions of elements may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like elements.

FIG. 1 is a perspective view schematically illustrating a multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure; FIG. 2 is a perspective view illustrating the multilayer ceramic capacitor of FIG. 1 from which terminal electrodes are separated; and FIG. 3 is an exploded perspective view illustrating a structure of internal electrodes in the multilayer ceramic capacitor of FIG. 1.

Referring to FIGS. 1 through 3, the multilayer ceramic capacitor 100 according to the exemplary embodiment in the present disclosure may include a ceramic body 110; a plurality of first and second internal electrodes 121 and 122, first and second external electrodes 131 and 132; first and second terminal electrodes 141 and 142; and first and second conductive adhesion layers 151 and 152.

The ceramic body 110 may be formed by stacking a plurality of dielectric layers 111 in a width direction thereof and performing a sintering process thereon.

Here, the respective adjacent dielectric layers 111 of the ceramic body 110 may be integrated with each other so that boundaries therebetween are not readily discerned without using a scanning electron microscope (SEM).

In addition, the ceramic body 110 may have a hexahedral shape. However, the present disclosure is not limited thereto.

In the exemplary embodiment of the present disclosure, for convenience of explanation, surfaces opposing each other in a thickness direction which is a vertical direction in which the dielectric layers 111 of the ceramic body 110 are stacked refer to an upper surface and a lower surface, respectively, and among them, the lower surface refers to a mounting surface.

Further, the ceramic body 110 is not specifically limited in dimensions, for example, may have a size of 1.6 mm×0.8 mm, or the like, to thereby configure the multilayer ceramic capacitor 100 having relatively high capacitance.

In addition, cover layers 112 and 113 having a predetermined thickness may be formed on both side surfaces of the ceramic body 110 which are outermost surfaces thereof in the width direction, as needed.

A thickness of one dielectric layer 111 may be optionally changed according to a capacitance design of the multilayer ceramic capacitor 100, and in detail, the thickness of one dielectric layer 111 may be configured to be about 1.0 μm after sintering. However, an exemplary embodiment in the present disclosure is not limited thereto.

In addition, the dielectric layer 111 may include a high-k ceramic material, for example, a barium titanate (BaTiO₃) based ceramic powder, or the like. However, the present disclosure is not limited thereto.

An example of the BaTiO₃-based ceramic powder may include (Ba_(1-x)Ca_(x))TiO₃, Ba (Ti_(1-y)Ca_(y))O₃, (Ba_(1-x)Ca_(x)) (Ti_(1-y)Zr_(y))O₃, Ba(Ti_(1-y)Zr_(y))O₃, and the like, in which Ca, Zr, or the like, is partially dissolved in BaTiO₃. However, the present disclosure is not limited thereto.

Meanwhile, in addition to the ceramic powder, the dielectric layer 111 may further contain ceramic additives, organic solvents, plasticizers, binders, dispersants, and the like.

As the ceramic additive, for example, a transition metal oxide or carbide, a rare earth element, magnesium (Mg), aluminum (Al), or the like, may be used.

The first and second internal electrodes 121 and 122 may be formed and stacked on ceramic sheets forming the dielectric layers 111, and then sintered, such The first and second internal electrodes 121 and 122 are alternately disposed in the ceramic body 110 with each of the dielectric layers 111 interposed therebetween.

The first and second internal electrodes 121 and 122, which are a pair of electrodes having different polarities, may be disposed to face each other in a direction in which the dielectric layers 111 are stacked and may be electrically insulated from each other by the dielectric layers 111 interposed therebetween.

The first and second internal electrodes 121 and 122 may include first and second capacitance parts 121 a and 122 a forming a capacitance by overlapping with adjacent internal electrodes, and first and second lead-out portions 121 b and 122 b exposed through both end surfaces of the ceramic body 110 in a length direction thereof by extending portions of the first and second capacitance parts 121 a and 122 a.

The first and second lead-out portions 121 b and 122 b of the first and second internal electrodes 121 and 122 alternately exposed through both end surfaces of the ceramic body 110 may be electrically connected to the first and second external electrodes 131 and 132, respectively, on both end surfaces of the ceramic body 110 in the length direction.

Here, the first and second internal electrodes 121 and 122 may be formed of a conductive material, for example, a material such as nickel, a nickel alloy, or the like. However, the present disclosure is not limited thereto.

According to the configuration as described above, when predetermined voltages are applied to the first and second external electrodes 131 and 132, electric charges may be accumulated between the first and second internal electrodes 121 and 122 facing each other.

Here, a capacitance of the multilayer ceramic capacitor 100 may be in proportion to an overlapped area of the first and second capacitance parts 121 a and 122 a of the first and second internal electrodes 121 and 122 which are overlapped with each other in a direction in which the dielectric layers 111 are stacked.

The first and second external electrodes 131 and 132 may be formed by sintering conductive pastes for an external electrode containing copper (Cu) so as to have an excellent electrical property and provide high reliability such as excellent heat cycle resistance, moisture resistance, and the like. However, the present disclosure is not limited thereto.

The first and second external electrodes 131 and 132 may only be disposed on portions of both end surfaces of the ceramic body 110 in the length direction to which the first and second lead-out portions 121 b and 122 b of the first and second internal electrodes 121 and 122 are exposed, and may be connected to the first and second lead-out portions 121 b and 122 b, respectively, to thereby be electrically connected to the first and second internal electrodes 121 and 122.

Here, the first and second external electrodes 131 and 132 may include band portions extended onto portions of both side surfaces of the ceramic body 110 in the width direction. The band portions may improve adhesive strength of the first and second external electrodes 131 and 132.

Meanwhile, the first and second external electrodes 131 and 132 may have plating layers (not shown) formed thereon. As an example, the plating layers may include first and second nickel (Ni) plating layers formed on the first and second external electrodes 131 and 132, respectively, and first and second tin (Sn) plating layers formed on the first and second nickel plating layers, respectively.

The first and second terminal electrodes 141 and 142 may be formed in an ‘L’ shape, and may include first and second horizontal portions 141 b and 142 b disposed below the ceramic body 110 and first and second vertical portions 141 a and 142 a extended from edges of the first and second horizontal portions 141 b and 142 b upwardly thereof, and contacting the first and second external electrodes 131 and 132 to be electrically connected to each other.

Here, the first and second vertical portions 141 a and 142 a may be disposed to be spaced apart from both end surfaces of the ceramic body 110 in the length direction. In addition, the first and second horizontal portions 141 b and 142 b may be surface-treated by nickel/tin, nickel/gold plating, or the like, to have excellent contactability with solder at the time of mounting the capacitor on the board.

Further, the first and second horizontal portions 141 b and 142 b may be disposed to be spaced apart from the lower surface of the ceramic body 110.

In this case, since the first and second terminal electrodes 141 and 142 are in direct contact only with the first and second external electrodes 131 and 132 having a significantly small area as compared to that of the end surfaces of the ceramic body 110 in the length direction, acoustic noise may be significantly reduced.

The first and second terminal electrodes 141 and 142 may absorb mechanical vibrations caused by the piezoelectric property of the multilayer ceramic capacitor 100 using elastic force, such that the vibrations may be prevented from being transferred to the board on which the multilayer ceramic capacitor is mounted, which may reduce acoustic noise.

In addition, mechanical stress caused by deformation of the mounting board may be absorbed by elastic force of the first and second terminal electrodes 141 and 142, and mechanical stress reaching the ceramic body 110 may also be reduced, such that defects such as cracks and the like, or damages occurring in the ceramic body 110 may be prevented, whereby reliability may be improved.

In addition, according to the exemplary embodiment in the present disclosure, sufficient elastic force may be obtained by the first and second terminal electrodes 141 and 142, such that even in a case in which the first and second horizontal portions 141 b and 142 b of the first and second terminal electrodes 141 and 142 and the lower surface of the ceramic body 110 may contact each other, or when they are spaced apart from each other, a significantly decreased interval therebetween may be maintained, whereby a product may have significantly decreased height.

The first and second conductive adhesion layers 151 and 152 may be interposed between the first and second external electrodes 131 and 132 and the first and second vertical portions 141 a and 142 a of the first and second terminal electrodes 141 and 142, and may connect the first and second external electrodes 131 and 132 and the first and second terminal electrodes 141 and 142 to each other to be electrically connected to each other, respectively.

Meanwhile, in the exemplary embodiment of the present disclosure, when defining a height (H) of the external electrodes to a width (W) of the ceramic body in order to more reduce acoustic noise, W/H may be 5.8 or less.

Experimental Example

Multilayer ceramic capacitors according to Embodiment in the present disclosure and Comparative Examples of the present disclosure were manufactured as follows.

Slurry containing a powder such as barium titanate (BaTiO₃), or the like, was applied onto a carrier film and dried to prepare a plurality of ceramic green sheets.

Then, the internal electrodes having the lead-out portions alternately exposed through both end surfaces of the ceramic green sheet were formed by applying a conductive paste for nickel internal electrodes to the ceramic green sheet using a screen.

The plurality of ceramic green sheets on which the internal electrodes are disposed were stacked to form a laminate, and the laminate was isostatically pressed.

Then, the laminate of which the pressing process was completed was cut into individual chips, and the cut chips were subjected to a debinding process while maintaining a temperature of about 230° C. for about 60 hours in an air atmosphere.

Next, the ceramic bodies 110 each having a width and a height illustrated in Table 1 below were prepared by performing a sintering process under reduction atmosphere having oxygen partial pressure.

After sintering, the ceramic body had a size of length×width (L×W) of about 1.6 mm×0.8 mm(L×W, 1608 size) and about 2.0 mm×1.25 mm (L×W, 2012 size).

Then, the external electrodes were formed on the both end surfaces of the ceramic body in the length direction to be connected to the lead-out portions, respectively, to thereby manufacture the multilayer ceramic capacitor.

Here, a manufacturing tolerance was determined to be within a range of ±0.2 mm, and when the manufacturing tolerance is satisfied, measurement of acoustic noise was performed.

TABLE 1 # W(mm) H(mm) W/H SP(dB) 1 0.87 0.06 14.5 26 2 0.87 0.09 9.7 24 3 0.87 0.15 5.8 14 4 0.87 0.23 3.8 9 5 0.87 0.32 2.7 9 6 1.26 0.10 12.6 25 7 1.26 0.16 7.9 19 8 1.26 0.27 4.7 11 9 1.26 0.36 3.5 10 10 1.26 0.50 2.5 9

In Table 1, SP indicates a value of acoustic noise.

Data of Table 1 indicate a width (W) of the ceramic body 110 measured at the end surface of the ceramic body 110 of the multilayer ceramic capacitor 100 in the length direction, and a distance (H) from the lower surface of the ceramic body 110 to a lower end of the first or second external electrode 131 or 132 as illustrated in FIG. 4.

In order to measure acoustic noise, after the terminal electrodes of an exemplary embodiment in the present disclosure were attached onto the first and second external electrodes, one sample (multilayer ceramic capacitor) per board for measuring acoustic noise was mounted on the board in a vertical direction, and the board was installed on a jig for measurement.

In addition, a direct-current (DC) voltage and voltage fluctuation were applied to both terminals of the samples installed on the jig for measurement by using a direct-current (DC) power supply and a function generator. Acoustic noise was measured by microphone directly installed on the printed circuit board.

Referring to Table 1 above, it may be confirmed that samples 3 to 5, and samples 8 to 10 are Embodiments in the present disclosure in which W/H is 5.8 or less, and in these cases, the acoustic noise is significantly reduced to be less than 15 dB.

It may be appreciated that samples 1, 2, 6 and 7 are Comparative Examples in which W/H is more than 5.8, and in these cases, acoustic noise is more than 15 dB, and therefore, the acoustic noise may not be reduced as compared to Embodiments in the present disclosure.

Therefore, it may be appreciated from the present experimentations that when designing that W/H is 5.8 or less, acoustic noise may be significantly reduced.

FIG. 5 is a perspective view illustrating another example of the terminal electrodes in the multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure.

Referring to FIG. 5, the first and second terminal electrodes 143 and 144 according to the exemplary embodiment in the present disclosure may include first and second upper horizontal portions 143 c and 144 c extended from the first and second vertical portions 143 a and 144 a to portions of the upper surface of the ceramic body 110.

In addition, the first and second terminal electrodes 143 and 144 may include a pair of first and second guide portions 143 d and 144 d extended from both side edge portions of the first and second vertical portions 143 a and 144 a onto portions of both side surfaces of the ceramic body 110 in the width direction, respectively.

The first and second upper horizontal portions 143 c and 144 c and the first and second guide portions 143 d and 144 d may increase positioning accuracy to improve manufacturing efficiency when the first and second terminal electrodes 143 and 144 are disposed on both end surfaces of the ceramic body 110 in the length direction.

Here, reference numerals 143 b and 144 b refer to the first and second horizontal portions of the first and second terminal electrodes 143 and 144 according to the exemplary embodiment in the present disclosure, respectively.

FIG. 6 is a perspective view illustrating another example of the terminal electrodes in the multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure.

Referring to FIG. 6, first and second terminal electrodes 145 and 146 according to an exemplary embodiment in the present disclosure may include first and second upper horizontal portions 145 c and 146 c extended from the first and second vertical portions 145 a and 146 a to portions of the upper surface of the ceramic body 110, respectively.

The first and second upper horizontal portions 145 c and 146 c may increase positioning accuracy when the first and second terminal electrodes 143 and 144 are disposed on both end surfaces of the ceramic body 110 in the length direction.

In addition, the first and second terminal electrodes 145 and 146 may have recess portions formed on both sides of the first and second vertical portions 145 a and 146 a in the width direction of the ceramic body 110, respectively.

In this case, the recess portions may decrease an area in which the first and second vertical portions contact the first and second external electrodes 131 and 132 each other, such that vibrations transferred from the first and second external electrodes 131 and 132 may be decreased.

Here, reference numerals 145 b and 146 b refer to the first and second horizontal portions of the first and second terminal electrodes 145 and 146 according to the exemplary embodiment in the present disclosure.

FIG. 7 is a perspective view illustrating another example of the terminal electrodes in the multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure.

Referring to FIG. 7, first and second vertical portions 147 a and 148 a of first and second terminal electrodes 147 and 148 according to the exemplary embodiment in the present disclosure may have a cross (+) shape.

In this case, recess portions formed in the first and second terminal electrodes 147 and 148 may decrease an area in which the first and second vertical portions 147 a and 148 a contact the first and second external electrodes 131 and 132 each other, such that vibrations transferred from the first and second external electrodes 131 and 132 may be decreased.

Here, a sufficient contact area with the first and second external electrodes 131 and 132 may be secured by the first and second guide portions 147 d and 148 d, and therefore, bonding strength may be improved.

In addition, when the bonding strength between the first and second terminal electrodes 147 and 148 and the first and second external electrodes 131 and 132 is secured at a predetermined level as described above, acoustic noise may be further reduced by elastic force of the first and second vertical portions 147 a and 148 a.

Further, the first and second terminal electrodes 147 and 148 may include first and second upper horizontal portions 147 c and 148 c extended from the first and second vertical portions 147 a and 148 a to portions of the upper surface of the ceramic body 110.

In addition, the first and second terminal electrodes 147 and 148 may further include a pair of first and second guide portions 147 d and 148 d extended from both side edge portions of the first and second vertical portions 147 a and 148 a onto portions of both side surfaces of the ceramic body 110 in the width direction, respectively.

The first and second upper horizontal portions 147 c and 148 c and the first and second guide portions 147 d and 148 d may increase positioning accuracy when the first and second terminal electrodes 147 and 148 are disposed on both end surfaces of the ceramic body 110 in the length direction.

Here, reference numerals 147 b and 148 b refer to the first and second horizontal portions of the first and second terminal electrodes 147 and 148 according to the exemplary embodiment in the present disclosure.

FIG. 8 is a lateral cross-sectional view schematically illustrating a board on which a multilayer ceramic capacitor according to an exemplary embodiment in the present disclosure is mounted.

Referring to FIG. 8, a board on which the multilayer ceramic capacitor 100 according to the exemplary embodiment in the present disclosure is mounted may include a circuit board 210 on which the multilayer ceramic capacitor 100 is mounted, and first and second electrode pads 221 and 222 formed on the circuit board 210 to be spaced apart from each other.

The multilayer ceramic capacitor 100 may be bonded and electrically connected to the circuit board 210 by solders 231 and 232 in a state in which the first and second horizontal portions 141 b and 142 b of the first and second terminal electrodes 141 and 142 disposed on a lower surface which is the mounting surface of the ceramic body 110 are positioned to contact the first and second electrode pads 221 and 222 of the circuit board 210, respectively.

As described above, when voltages having different polarities are applied to the first and second external electrodes 131 and 132 disposed on both end portions of the multilayer ceramic capacitor 100 in a state in which the multilayer ceramic capacitor 100 is mounted on the circuit board 210, the ceramic body 110 may be expanded and contracted in the thickness direction due to an inverse piezoelectric effect of the dielectric layers 111, and both end portions of the first and second external electrodes 131 and 132 may be contracted and expanded in directions opposite to those of expansion and contraction of the ceramic body 110 in the thickness direction, due to a Poisson effect.

The contraction and expansion may cause vibrations. In addition, the vibrations may be transferred from the first and second external electrodes 131 and 132 to the circuit board 210. Therefore, sound may be radiated from the circuit board 210, which becomes acoustic noise.

According to the exemplary embodiment in the present disclosure, piezoelectric vibrations transferred to the circuit board through the first and second external electrodes 131 and 132 of the multilayer ceramic capacitor 100 may be absorbed by elastic force of the first and second terminal electrodes 141 and 142, and mechanical stress caused by warpage of the circuit board, and the like, may be absorbed by the first and second terminal electrodes 141 and 142, such that acoustic noise may be reduced.

In addition, when the first and second horizontal portions 141 b and 142 b of the first and second terminal electrodes 141 and 142 are disposed to be spaced apart from the lower surface of the ceramic body 110, since the first and second terminal electrodes 141 and 142 are in direct contact only with the first and second external electrodes 131 and 132 having a significantly small area as compared to that of the end surfaces of the ceramic body 110 in the length direction, acoustic noise may be significantly reduced.

As set forth above, according to exemplary embodiments in the present disclosure, the external electrodes may have an area smaller than that of the end surfaces of the ceramic body in the length direction, and elastic force of the terminal electrodes bonded to the external electrodes and spaced apart from the end surfaces of the ceramic body in the length direction may absorb vibrations transferred through the external electrodes of the ceramic body, such that acoustic noise may be reduced.
